Stop seal plate leaks at the source with the Swimables SW-21-357 Black Seal Plate Gasket, purpose-made for Pentair Whisperflo and Intelliflo pool pumps. This flexible gasket sits between the seal plate and pump housing, compressing into a continuous watertight barrier that blocks drips and prevents air from being drawn into the system. Formed from resilient, chemical-resistant rubber compound, it maintains its shape and elasticity through countless heating and cooling cycles, delivering dependable sealing performance season after season. Swapping in a fresh gasket during routine pump maintenance is one of the most cost-effective steps you can take to protect motor components and keep priming strong.

Key Benefits

• Complete Watertight Barrier: Compresses evenly between the seal plate and housing to form a continuous seal that blocks both water leaks and unwanted air ingestion.
• Resilient Rubber Compound: Made from a flexible material that withstands temperature swings, UV exposure, and constant contact with pool chemicals without hardening or cracking.
• Keeps Your Pump Primed: An airtight gasket seal prevents air pockets from forming in the volute, so your pump maintains consistent suction and flow rates.
• Smart Preventive Maintenance: Replacing this low-cost gasket during pump servicing helps you avoid expensive motor damage and lost swim time caused by slow leaks.
